  1. Hi @RHa, I apologize for the delay. I have reached out to @Wyllyam about a potential update. Thank you, JColvin
  2. Hi @autoamp, The main thing you would need to look for (and it appears you have already done so) would be to check that whatever connectivity you are planning to use lines up with the 15-pin flat flexible cable connector present on the Pcam 5C. Otherwise I would check that the power supplies are set up since the schematic shows that the Pcam 5C uses a 3.3V line to generate the needed 1.8V and 2.8V for the module. Thank you, JColvin
  3. Hi @JIBI3731, Are you using PetaLinux at all or Vitis HLS or something like that? Normally to creatte the appropriate file and program flash, you would follow these steps that are nicely outlined in this specific forum post here: https://forum.digilentinc.com/topic/5232-problem-with-how-to-store-your-sdk-project-in-spi-flash-tutorial/?do=findComment&comment=21569. These steps were written prior to the existence of Vitis, but the steps are still the same. Let me know if you have any questions. Thanks, JColvin
  4. Thank you for sharing what you found!
  5. Hi @CurtisNotestine, Are you following a 'Hello World' design in particular? For the 2020.1 version of the Xilinx tools, I usually direct users to the guides the Digilent has on our Wiki here: https://reference.digilentinc.com/reference/programmable-logic/guides/start. The errors you are getting imply that the .xdc file does not have the proper pins uncommented and named correctly. Are you using HDL or a Block Design flow? If you are using a Block Design flow, did you install the Digilent board files for the Nexys A7 100T? Thanks, JColvin
  6. Hi @jeffdecola, Connecting GPIO between the Raspberry PI and a Pmod port on an Arty S7 can work since they both operate at 3.3V. Be sure to connect the grounds between the two boards though to better ensure you have a common reference voltage. I would also recommend using JC or JD on the Arty S7 as both of those Pmod ports have current limiting resistors to help prevent any problems (though I believe the gpio pins on both sets of boards are current limited to begin with). Thanks, JColvin

    Hi @felayyach, You can install the board files by following the guide that is linked in this thread. Thank you, JColvin
  8. Hi @amehdi, I got confirmation that the USRB B205mini-i that Digilent sells and the one Ettus sells are the same board with the same specifications. You will be free to use the enclosure that Ettus sells separately, https://www.ettus.com/all-products/usrp-b205mini-i-enclosure/, on the module that Digilent sells. Based on the Ettus page for the enclosure, all it does is increase the safe operating temperature range. Thank you, JColvin
  9. Despite our hopes and effort to create an innovative and low-cost T&M solution, we’ve received consistent negative feedback on the OpenScope MZ and OpenLogger regarding overall reliability that has led us to determine that it is not up to our high standards for our test and measurement products. Unfortunately, we are unable to fix many of the issues, so we have made the difficult decision to pull both products, and related accessories from our shelves. This will allow us to ensure we can continue to deliver on the Digilent brand promise and focus our efforts on expanding our popular a
  10. Hi @Leo_W, That is what I am confused about as well. If the same demo code's bitstream runs on a different Nexys 4 DDR just fine and the seven segment display and LEDs light up as expected, but if you use a different project entirely on this particular board and it's LEDs and seven-segment display then work as expected, I am at a loss as to what the problem might be as both hardware and software problems are ruled out. I will think on this a bit more to see if I can come up with some other sort of thing to troubleshoot. Thank you, JColvin
  11. Hi @DigbyT, I believe the bitstream comes from the Base Linux project on our GitHub: https://github.com/Digilent/Zybo-Z7-20-base-linux and is used as the source to configure the FPGA after it has booted up (since the FPGA itself is volatile, unlike QSPI or the SD card). @Ionel would be better able to clarify the details on this. Thanks, JColvin
  12. Hi @User5717, Like you surmised, something likely became shorted, though it's hard to say what. You say the FPGA "connects and disconnects". Do you mean that it briefly shows up as a COM port in the Device Manager (presuming you are on Windows) and then disappears? Or does the Device Manager not recognize that anything is plugged in? I'm guessing Vivado is not able to recognize a detected board through it's Hardware Manager. Is the Arty S7 still receiving power when you connect it (i.e. is the power LED on)? And on the chance that you have not overwritten the flash memory for on
  13. Hi @Leo_W, What version of Vivado are you using and did you use the release of this project (available on our GitHub here: https://github.com/Digilent/Nexys-4-DDR-GPIO/releases). The program should work fine on other versions of Vivado besides the one the latest version of the release is for (2018.2), though you would likely need to regenerate the bitstream for it. Thanks, JColvin
  14. Vivado 2019.1 is available; it's just listed in the archive section: https://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/vivado-design-tools/archive.html.
